Weekend game deals: Everything and a partridge in a pear tree

With holiday promotions in full swing, it'd probably be easier to tell you what isn't on sale this weekend. Most sites are swapping their best deals at least once a day, so you'll have to keep an eye on things if you want to snag a particularly handsome discount. As of writing, you'll find solid deals on FTL: Faster Than Light, LA Noire, Left 4 Dead 2, XCOM: Enemy Unknown, Sleeping Dogs, BioShock 1 & 2, Spec Ops: The Line, 2K strategy titles, Rayman: Origins, Torchlight II, Alan Wake, Red Orchestra 2, and both Witcher titles. Also, the Humble Indie Bundle 7 continues with three more games added this week.
